摘要： The invention provides a method and system for content-based filtering of multicast information. A set of sources (S) which desire to distribute potentially large numbers of categories of differing information each associates a content descriptor (CD) with messages including information in those categories, so that a set of recipients (R) can receive information in at least some of those categories. A mapping server (M) associates a multicast address (MA) and a content mask (CM) with each content descriptor, so that network elements (N), such as routers, in the network can distribute only those messages which are of interest to recipients in multicast distribution trees for those multicast addresses. Each source generates content descriptors for each differentiable topic in a tree structured hierarchy, and obtains a multicast address and a content mask for the broadest content descriptor it is capable of distributing. Each recipient obtains the associated source, multicast address, and content mask, for each content descriptor of interest, and uses that information to join the multicast distribution tree for that information. Each network element between the source and the recipient determines what information it must forward for further distribution in response to the content descriptors, content masks, multicast addresses, and multicast distribution trees.

摘要： Devices, methods and instructions encoded on computer readable medium are provided herein for creation of an overlay network on a non-multicast or source specific multicast (SSM) core. In one example, virtual private network (VPN) adjacencies are established between an adjacency server and one or more edge devices each located at different network sites. A unicast replication list is then generated at the adjacency server. The unicast replication list includes the Internet Protocol addresses for each of the edge devices having VPN adjacencies with the adjacency server. The unicast replication list is then advertised to each of the edge devices for use in establishing VPN adjacencies with one another.

摘要： Methods and apparatus for source rooted multicast (SRM) are provided. As defined herein, SRM generally refers to associating outgoing interface lists (OILs) in the forwarding entry with the source address instead of the group address and aggregating the resulting multicast forwarding states. In this manner, the amount of forwarding state may be reduced, especially in deployments where many hosts are all running the same application and using the same group. One example method generally includes—for each of a plurality of multicast forwarding states associated with a multicast group, wherein each multicast forwarding state is referenced by a source address representing a multicast source and is associated with an outgoing interface list—associating the outgoing interface list with the source address; and aggregating the two or more of the multicast forwarding states having the outgoing interface lists associated with the source addresses to form one or more aggregated forwarding states.

摘要： In one embodiment, an indication of a fault condition is received relating to a first service running on a physical device in a computer network. The first service is associated with a first virtual device context defined on the physical device. Then, the first service is disabled without affecting operation of a second service on the physical device. The second service is associated with a second virtual device context defined on the physical device. In another embodiment, a first virtual device context is created on a physical device in a computer network. Then, a second virtual device context is created on the physical device. The first virtual device context may then be managed independently of the second virtual device context such that resources assigned to a virtual device context are managed without affecting management of another virtual device context.

摘要： Various systems and methods for rerouting multicast traffic in response to detecting imminent network disruption are disclosed. One method involves detecting an imminent topology change and, in response, identifying a new multicast distribution tree for a multicast group. A join message for the multicast group is then sent towards a root of the new multicast distribution tree. Multicast traffic addressed to the multicast group continues to be forwarded via the current multicast distribution tree, subsequent to sending the join message. The multicast traffic is not forwarded via the new multicast distribution tree until one or more multicast data packets have been received via the new multicast distribution tree.

摘要： Systems and methods for automatically controlling efficient operation of a plurality of network appliances operatively linked and networked to balance network traffic load across a plurality of network appliances that are selectively enabled. The system facilitating performance of the method includes at least a plurality of network appliances operatively connected to a switch and controlled by a network access control module. During system operation, at any given moment in time, the plurality network appliances operate in one of two modes, fully operational or stand-by. The network appliances of the plurality that are fully operational and thereby consuming full operational power depends upon the network traffic load at any given moment in time. The network appliances functioning in a stand-by mode consume low power levels which are sufficient to allow a network appliance in stand-by mode to receive a command signal directing it to switch from stand-by to full operational mode.

摘要： A method and system for translation of virtual private network (VPN) addresses over a provider network are disclosed. The method includes creating a multipoint tunnel extending between customer edge routers in a VPN network and over the provider network. The multipoint tunnel is identified with a multicast address and multicast packets are sent over the tunnel to identify tunnel endpoints at customer edge routers within the VPN. The method further includes converting, at one of the customer edge routers, a VPN join message to a provider join message and sending it over the provider network.
